The Consumers International (CI) battle against marketing of unhealthy food to children has gathered support from domestic groups as well. The London-based CI is an independent consumer network with over 220 member organisations in 115 countries.

Other than these, participating organisations are from the Philippines, Fiji, Malaysia and Korea.
